Hello
My project is to use a two BLE Redbear Labs Nano v2. One as a key fob and one SPI connected to a Arduino Nano / Particle Photon. The BLE key fob remote has 5 push buttons. Press a button on the key fob and it sends a signal to the other BLE Nano V2 connected to a LED lights up on an Arduino Nano / Particle Electron. No need for an app. Just master / slave with the two BLE Nanos to the a...

The application has to be able to communicate with the tracker, with the GPS and Bluetooth modules installed and give the end user an idea of where the keys are located. The tracker will also have LEDs and a buzzer so the user has to be able to trigger them if the trackers is still connected via Bluetooth.

I need to develop my own hardware, based on the rock64 board.
I need to use rock64 as a base and include some components like wifi, bluetooth, accelerometer, gps and 4g, all on the same card. You will need to remove other rock64 components that will not be used in the project. I need a custom board.
The board needs to be as small as possible, very close to the size of rock64.

I am looking for an app developer that uses an open IDE/platform to help me develop and App which will control and monitor an electronic device using a Microchip RN4871 Bluetooth Module.
I will be doing the work on the device side and will want to do a lot of the visual app stuff myself so it's important that we can work on the app together with the same set of development tools.
You wi...

I require an android application (Android 5>Current) that will configure a hardware device via bluetooth. I will provide protocol information and functional description. The communications will be bi-directional so the application will need to parse returned configuration data and display to the user.
